Sibert Solar Begins Distribution of Advanced Energy’s Three-Phase String and Single-Phase Residential Inverters

Metzingen, Germany, August 12, 2014—Advanced Energy Industries, Inc. (Nasdaq: AEIS) and technical photovoltaic (PV) solar expert Sibert Solar today announced a distribution agreement for Sibert Solar to distribute Advanced Energy’s three-phase string inverters and single-phase residential inverters as part of its cost-effective procurement solutions within the United Kingdom. Sibert Solar’s product portfolio, now including Advanced Energy inverters, has been carefully selected and developed to provide its customer base with productive yet cost-effective procurement solutions.

The AE 3TL, a reliable three-phase string inverter with a peak efficiency of up to 98.7 percent and versatile data monitoring options, can be installed in a distributed architecture throughout a solar array to save space and increase project yield for solar installers, site designers and project developers. The AE 3TL can be applied to projects of wide-ranging sizes, from small commercial rooftop to large multi-megawatt ground-mount systems.

Advanced Energy’s single-phase string inverters are suitable for small rooftop systems or for expanding larger systems (for example in the case of shading). Even at low irradiation, the inverters achieve an efficiency of up to 98.6 percent. With its lightweight design, convection cooling and high power density, the inverter can be installed quickly and easily, and requires little-to-no maintenance. Through its robust line of inverters, Advanced Energy is demonstrating its commitment to offering customers unparalleled design flexibility for the solution that best addresses their solar project needs.

"Sibert Solar is extremely experienced in the United Kingdom solar industry, and we’re very pleased to be expanding our market presence here by partnering with a fellow company that understands the value of offering quality products,” said Jason Nicholls, U.K. country manager at Advanced Energy. “As one of the top inverter manufacturers worldwide, Advanced Energy is excited to share its inverter solutions and excellent after-sales package to meet the diverse design application needs of our expanding U.K. customer base.”

“Advanced Energy’s high-performance inverters are feature-packed, offering tangible value for customers wishing to utilise a premium product,” said Andy O’Leary, business development manager at Sibert Solar. “Sibert Solar’s ethos is to provide total customer satisfaction through thorough pre- and post-sale support, including system-design, commissioning, training, service and spares. Our partnership with Advanced Energy reflects and maintains this ethos.”
